Call it before `PUT /v1/sso/provider`. The upsert is the call that can lock an organization out of its own login screen; this one costs nothing, so there is no reason to skip it. The response is a report, not a yes/no: it names what it could and could not verify. Failures: - `400` — the candidate configuration is malformed enough that it cannot be checked at all. ## OpenAPI ````yaml /en/openapi/v3-current/AM-identity.yaml post /v1/sso/provider/preflight openapi: 3.1.0 info: contact: name: Lerian Studio url: https://lerian.studio description: OpenAPI 3.1 surface for the Access Manager identity component. license: name: Lerian Studio General License title: Plugin Access Manager — Identity API version: v1 servers: - url: https://identity.sandbox.lerian.net security: [] tags: - description: >- M2M-only: each plugin declares its own permissions, roles and M2M contract, and the server reconciles them. name: Declarations - description: >- A tenant administrator's customers.
